Splitting Tractor Questions

How do folks keep the engine side of the tractor from tilting side to side on the front axle pivot when split?

My tractor's transmission is a disabled multi-power (read mechanically locked in high w/no hydraulic clutch pack pressure) and I think all I will have to replace is the lip seal on the input shaft.

Anything else I should consider checking/replacing while I am in there? The clutch is in good shape.

Any tips, advice, etc would be appreciated.

Thanks in advance,
Bill

The tractor does not free wheel down hill and has engine hold back. If I park it on a slope, it does not move after the engine is shut down. The serial number of the tractor indicated multipower. There is a slot on the dash where the MP lever was. Either the transmission has been swapped to a "normal" 6 speed or the multipower has been mechanically locked in high. I don't recall the exact procedure, but I have read that one can weld the high range gear in such a way that it does not require the clutch pack to move it into position. I think this is what is going on with my tractor. Futher, the multipower pump is gone, but the bracket that held it in place is still there.

When I split the tractor, I will know for sure.

Thanks,
